VEHICLE-WHEEL.

Specification of Letters Patent.

Patented July 6, 1909.

Application filed February 101906. Serial No. 300,359.

To allwhom 'it may concern: f Be it known that I, JOHN SiNNoTT, a citizen of the United States, residing at Philadel hia, county of Philadelphia, and State4 of ennsylvania, have invented a new and useful .lm rovement which the ollowing is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of thisspeciication.

In a patent issued to me May 15, 1906, No. 820,741, there is set forth a construction for vehicle wheels adaptedto absorb shocks to the vehicle without the use of pneumatic or other similar tires, the said construction comprising inner shoes engaging and mov-m able circumferentally relatively to outer shoes secured tothe rim, and tubular spokes secured to the hub and engaging and movable radially relatively to the inner shoes,

.therebeing'springs between the spokes and inner shoes and between the inner shoes and outer shoes adapted to yield to permit said movements and to restore the movable parts to theirnormal positions.

The present invention has for its object to improve the said construction and particularlyr to construct and arrange the rim and shoes so that the latter will be inclosed and protfcted by the rim and rendered dust roo \ In the drawings: Figure 1 elevation, partly in. section, improved Wheel;` Fig. 2 is is a detailed side of a part of 'Lily a sectional view taken lon itudinally through a spoke and transverse y through the shoes, rim and tire.

The outer shoes are of the rim that nated the cuter rim. The tirec is secured to the outer rim b in the usual way.

i Each outer shoe comprises side flanges d, artly cut away; end flanges c; a slotted horizontal-web f; and lect d extending through, and flush with the outside of, the rim. The side flanges are tapered inwardly and upwardly at their upper ends above the web f` Egch inner shoe comprises a llat plate g having sides ta ering downwardly and outwardly, the wi `th and sha se of the shoe .being such as 4to lit within t e shallow groove or guide formed by the web and side an es d of the lower shoe; The inner snoe is a so provided with flanges 7i overhang'ing its en ds and with a central projection t extending socuredto a part b in Vehicle-Wheels, of l within' which extend will be hereinafter desige-V through and beneath the slot in. the web f. Secured to the projeotionwfi are pins j projecting endwise therefrom. and confined the end ilan es 'e4 of the lower shoes, coil springs The inner shoes also'coinprise radially inwardly extending hollow ortubular, arms Z the tubular spokes m. The hub is made of two arts or sections n, a, abutting against eacli other, the said parts havirf` annularjlanges o, '0, lprovided with 'complementary recesses lfoi-min a sopket to receive the 4tubulaixsp'oke m. gThe, spokes m are held in place, and the two parte of the hub secured together, by means of bolts p extending through the abutting flanges and arranged alternately' with the spokes. A

z is a' spring extending throughout each tubular spoke and abutting at its opposite ends afrainst the hub inner s ioe.

The connection described between th inner shoes .and the` hub is specifically the same as that set forth in my said prior application.

The remaining. art ofthe rim, which l call the inner rim, an which is made in sections consists of side flanges a adaptedv to rest within and upon the outer riin to the outer shoes, and a web :i: connecting the inner ends of the side 'ianges. rilhis web is cut away to accommodate the tubulararnis l of the inner shoes and also to leave a space in front and back of the tubular arms l to permit the inner shoes to slide circumferentiully, or more accurately, at right angles tothe radius in the riin thus ove angs the inner shoes at their i ends to permit the inner shoes to slide upon. l the inner riin as' well as upon the outer shoes. l, The part of the web .r of the inner rim overi hanging the ends of the inner shoes is thicle ened., and flattened on its under face, so as tov between. the projection4 t and are the between the inner rim and inner shoes.

l ln practice, the spokes of the wheel rido I backward or forwar with. relation to the rini in a circumferential direction depen dent upon i the point of a plication of force upon the rim, l the shoes sliding relatively upon each other in a longitudinal direction against the presi sure of one spring or l l shoes and inner rims also sliding longitudii nally upon each other. At the 'same time,

and the part g of thev pqlane of the wheel.- The inner, I.

the other, and the inner A Surrounding pins y, u

and bolted maintain at all times the proper sliding iit the part of the rim to which force is applied moves inwardly toward the hub by reason of the sliding connection between the spokes and the innei shoes, this relative movement of rim and hub being against the pressure of the springs within the spokes` The construction and arrangement of shoes and inner rim substantially conceals the shoes from view and effectively protects the shoes from dust. The inner rim may be made of aluminum in order to lighten the structure as a whole.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. A vehicle wheel comprising a hub, spokes, a rim, shoes secured to the rim, shoes `carried by the spokes and engaging both the first named hoes and the rim, and means permitting the last named shoes to move longitudinally with respect to both the first 'named shoes and the rim.

2. YA vehicle wheel comprising a hub, an outer rim and an inner rim secured together, inner and outer shoes within the rims, the former being carried by the s okes and the latte being secured to one oft e rims, guides on one of each air of shoes along which the other shoe is siidable longitudinally, and a flexible connection between the two shoes of 'a lpair tending to maintain them in normal re ation.

3. A vehicle wheel comprising a hub, an outer` rim, outer shoes secured thereto, an inner rim secured to the outer shoes, inner shoes slidable upon the outer shoes, a llexible connection between the two shoes of a pair, and spokes connecting the inner shoes and the hub. y

4. A vehicle wheel com rising a hub, spokes radiating from the hu i, a hollow rim, s ioes inserted in the rim and secured thereto, other shoes extending lwithin and engaging the rim and first-named shoes and movable circumferentially with respect to the rim and also movable radially with respect to the spokes, flexible connections between the lastnamed shoes and the spokes tending to maintain the hub central to the rim, and flexible connections between the two sets of' shoes tending to maintain them in normal relation.

5. A vehicle wheel comprising a hub, spokes radiating from the hub, a hollow rim,

,inner shoes extending within the rim, outer shoes within the rim and secured thereto and engaging and movable longitudinally along the inner shoes, springs between the outer and inner shoes, arms on the inner shoes engaging the spokes and slidable radially relatively thereto, and springs between the inner shoes and the spokes.
